PSTAT126 . Grigorian K 7 Days Ago

If you have a late pass time, just suck it up and take this class, but avoid it if possible. The lectures are utterly incomprehensible, but attendance counts a lot. Participating isn't hard if you just spam questions and hope a few are "profound." If he can put a name to your face by the end, you'll get a bonus.

The most annoying professor ever

Mandatory attendance and he can't explain anything properly. Avoid. Thinks he's funny but he's not.

Cannot understand anything he explains in class. Exams are way different than what we are actually taught in class. Thanks to the TA for being super helpful.

This was the worst class I have taken. Can be funny at times, but it doesn't make up for all the disorder and confusion. It's almost guaranteed that he loses track and forgets he is teaching a lecture. In my experience, my understanding and grade hinged off of the TA - exams were difficult and confusing. Participation is rewarded heavily. Good luck

Prof Grigorian is very passionate and lighthearted with the classes he teaches and will often explore interesting concepts (outside of usual class scope) or applications related to the course content. Curves classes based on class difficulty and is very lenient with grading. Make sure to attend lectures and PARTICIPATE ALOT, and youll get an A
